Key Functions and Benefits of Oil Pump Bush 201V93020-0405

Precision-Engineered for Optimal Oil Pump Performance

The Oil Pump Bush 201V93020-0405 serves as the critical bearing surface within the SINOTRUK oil pump assembly. It reduces rotational friction on the pump shaft, maintains precise clearance tolerances, and prevents metal-to-metal contact that would otherwise degrade pump efficiency over time.

• Extended Service Life: Manufactured from wear-resistant alloy material with superior hardness (HB 80–120), this oil pump bush withstands continuous high-speed rotation cycles exceeding 200,000 km before requiring inspection.
• Stable Oil Pressure Output: By maintaining tight shaft-to-housing clearances (typically 0.02–0.06 mm), the bushing minimizes internal leakage within the oil pump, ensuring consistent oil pressure delivery to all engine bearings and journals.
• Thermal Resistance: Designed to operate reliably in oil temperatures ranging from -30°C to +150°C, the bush maintains dimensional stability even during prolonged heavy-load hauling.
• Corrosion Resistance: The material composition resists degradation from acidic oil byproducts, extending replacement intervals and reducing total maintenance costs.
• Direct OEM Replacement: Drops into the existing oil pump housing without modification, eliminating machining time and ensuring immediate compatibility with the original assembly.

Frequently Asked Questions – Oil Pump Bush 201V93020-0405

What is the function of the Oil Pump Bush 201V93020-0405 in the engine?

The Oil Pump Bush 201V93020-0405 acts as a bearing sleeve inside the oil pump housing. It supports the pump drive shaft, reduces rotational friction, and maintains the precise clearance needed for the oil pump gears to generate consistent oil pressure. Without a properly functioning bush, the pump shaft wobbles, internal leakage increases, and oil pressure drops — potentially starving engine bearings of lubrication.

How do I know when the Oil Pump Bush 201V93020-0405 needs replacement?

Common indicators include fluctuating or low oil pressure readings at idle, unusual metallic noise from the oil pump area, and visible wear or scoring on the bush surface during engine overhaul. If the shaft-to-bush clearance exceeds 0.10 mm during inspection, replacement is recommended to prevent cascading damage to the oil pump gears and engine bearings.

Is this Oil Pump Bush compatible with non-SINOTRUK engines?

The 201V93020-0405 is specifically dimensioned for SINOTRUK MC-series engine oil pumps. While some Chinese engine platforms share design heritage, we strongly recommend verifying the OEM part number against your specific engine model before ordering. Our technical team can assist with cross-referencing if needed.

What material is the Oil Pump Bush 201V93020-0405 made from?

This bush is manufactured from a copper-based alloy composite that provides excellent anti-friction properties, thermal conductivity, and resistance to oil-borne contaminants. The bimetallic construction bonds the bearing layer to a steel backing for structural rigidity under load.

Can I order a small trial quantity before committing to bulk?

Yes. METTLEAD offers flexible minimum order quantities specifically designed for new customers who want to verify fitment and quality before scaling up. Trial orders ship with the same quality documentation and inspection reports as bulk production runs.
